Find LCM of 430,648,568,765 with Prime Factorization
| 2 | 430, 648, 568, 765 |
| 2 | 215, 324, 284, 765 |
| 2 | 215, 162, 142, 765 |
| 3 | 215, 81, 71, 765 |
| 3 | 215, 27, 71, 255 |
| 5 | 215, 9, 71, 85 |
| 43, 9, 71, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 43 x 9 x 71 x 17 = 168159240
Therefore, the lowest common multiple of 430,648,568,765 is 168159240.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
430 x 648 x 568 x 765 = 121074652800
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
430 : 1, 2, 5, 10, 43, 86, 215, 430
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
568 : 1, 2, 4, 8, 71, 142, 284, 568
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 430,648,568,765, is 1.
Now, the common factors can be found like this.
430:2x 5x 43
648:2x 2x 2x 3x 3x 3x 3
568:2x 2x 2x 71
765:3x 3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 121074652800/(1x720)
LCM = 121074652800/720
LCM = 168159240
Thus, we can understand that the LCM of 430,648,568,765 is 168159240.
